On "The Hills," Frankie Delgado's priorities amounted to partying until the sun came up (and not a second sooner), but it's safe to say those days are officially in the past. Delgado and his wife, Jennifer Acosta, welcomed a baby girl into the world on Sunday, and a snapshot that Frankie shared of his new bundle of joy yesterday on Instagram -- which features a closeup of the newborn's foot -- has us cooing. FOOTPRINTS ON OUR HEARTS, FRIENDS.

"I never knew how much I could love til I met you, the greatest gift of my life..." the proud papa captioned the photo, in which his fingers are softly nestled behind the baby's five tiny piggies. Frankie is the second "Hills" cast member to become a parent, and we hope it's not too much to expect that Baby Delgado and one of Kristin Cavallari's sons (she's due with her second in a hot minute) will hit it off, strike up an epic romance and live happily ever after. MAKE IT HAPPEN, GUYS!

Look at the lil' gal's first pic, and be sure to wish the happy couple congratulations!
